COUPLING.

SPECIFICATION forming part of Letters Patent No. 714,266, dated November25, 1902.

Application filed August 22, 1901. SerialNo. 72,883. (No model.)

To all whom it may concern: I

Be it known that I, EDWARD VOGEL, a citizen f the United States, and a resident of the borough of Manhattan, in the countyof'New York and State of New York, have invented certain new and useful Improvements in Couplings, of which the following is a specification.

lings, and has for its object the production,

. of couplings which will be applicable for seshows an elevation of the jaws. 1 2O curing tight joints for both liquids and gases or vapors without employing keys, wrenches, or any other devices not inherent in the apparatus.

Referringto the drawings, Figure 1 represents a partial vertical section through the longitudinal axis of my coupling. Fig. 2 Fig. 3 is a top view of Fig. 2. Fig. 4 representsan elevation of male portion of the coupling with a pipe. Fig.5 shows a section of Fig. 4 on the ;line w m. Fig. 6 shows an elevation of the screw-collar.

Fig. Us a plan view of Fig. 6. Fig. 8 is a partial section on the line 3 s of Fig. 1. Fig.9 is a partial section of Fig. 1

i i on the line 1 y. Fig. 10 shows an inside elevation of one member of the clamps.

The coupling comprises the tube or pipe A, to which are journaled the jaws B, constitut ing the female end of the coupling. The

tube or pipe 0 is hooked to the said jaws I tlOH of the apparatus. 3.5

over the tube A and constitutes the male por- A screw collar D turns on threads formed on the tube 0 and clamps the ends of the jaws B when in operative position. A pipe E is shown extending from the tube 0, although hose or any other conduit might be substituted, and if a hose it could be secured with clamps, aswill be.

explained for the hose connection of the tube or pipe A.

The tubes A and. Care joined by a flexible packing F, the construction of which will be a A spring b is fastened to the jaws B between the protecting-flanges b by means of screws or rivets 17 The jaws terminate in hooks b at their upper ends, andhandles b are formed on the outside faces of the said jaws.

grooved end, as a, of the tube A might be substituted for the purpose of attaching a hose. i

In the collaro. of the tube A there are openings of to hinge the hose-clamps G, the

that are in planes parallel to the longitudinal axis of the coupling and are clamped by means ofthe screw 9 and nut 9 hearing on the arms g, and the swinging bolt g with its jam-nuts g closing the opposite arms of the clamps. Ribs g extend from the inside of the faces of the clamps.

The screw-collar D turns on the threads of the tube 0 and clamps the ends of the jaws B.

The counterbore a of the tube A contains the packing F,which is mechanically secured in an annular cavity 0 in the tube 0, although the cavity might be made in the tube or pipe A. A ring F is expanded on the in ternal surface of the packing F and over the saidcounterbore c securing by these means a uniform opening through the coupling.

To look my coupling, the screw-collar D, having been screwed up on the central portion of the. tube 0, the hooks b of the jaws Bare forced over the hooks c of the tube 0, after which the collar D is screwed down to clamp the said jaws. The pressure of the wfluid or gas will force the packing F against free ends of which swing on hinges g in arcs It will be noted that the lower ends b of jaws to the pipe, asecond pipe axially in line the jaws are curved to approach the tube or with the first pipe, means to lock the two pipe A, and the bottom ends at I) would strike pipes, means to open the jaws, a collar on 15 the said pipe A if it should be attempted to the second pipe arranged to clamp the jaws 5 open the jaws too greatadistanoe.

York and State of New York, this 21st day of Having described myinvention, I desire to August, A. D. 1901. secure by United States Letters Patent and EDWARD VOGEL. [L. s] 10 claim Witnesses:
